Abstract: By combining with some certain low-temperature liquid nitrogen washing process project development and aiming to enhancing the washing efficiency of the core liquid nitrogen column as well as satisfying the specified process indexes, the nitrogen washing column plate number and structure are modified so as to achieve the goal of saving the nitrogen washing column manufacturing cost. By comprehensively taking the column plate efficiency into account and combining the design working condition verification as the theoretical method, the low-temperature liquid nitrogen washing principal and relevant process requirements are introduced first in this study; then the traditional calculation method to the liquid nitrogen column theoretical plate number is presented; moreover, the column plate efficiency and the algorithm are taken comprehensively into account; finally the improved algorithm to the liquid nitrogen column theoretical plate number is put forward and the corresponding verification under the design conditions has been carried out; the comparisons are in good agreement so as that the improved algorithm may obtain the more accurate results and meet the practical engineering design requirements.
